An Evaluation for the Location and Type of Hand Portable Fire Extinguisher Used on Board the AH-1 Army Helicopter

Abstract

The report evaluates various extinguishing agents for their desirability during inhabitable helicopter cockpit fires and states the most desirable agent as being Halon 1301. Graphs illustrating the concentration of Halon 1301 (% by volume) vs. time (seconds) for two extinguisher discharge conditions are presented. The applicability of the Air Force design criteria for fire extinguisher placement in the Army AS-1 helicopter is evaluated. The utilization of fire extinguishers in the Southeast Asia Conflict indicates that locating the extinguisher in the helicopter cockpit is not necessary. Relocation is an alternative to the total removal of the extinguisher and is recommended for safety reasons.
